This collaboration with artist Julian Opie was created for The Royal Ballet in 2008, and has been performed around the world to critical acclaim.nnOpie's LED figures walk across a screen above the stage for the duration of the ballet while underneath, the solos, duets and ensembles build to a mesmerizing climax, as six couples dance simultaneously within their separate squares of light.

Infra explores the feelings we keep hidden from those around us; a crowd surges past one woman who remains still, her private grief gut-wrenchingly evident for the audience, but unnoticed by the crowd.

This ground-breaking work remains one of McGregor's finest, and one of contemporary ballet's most emotionally resonant pieces.
